Description

Welding device for screen disc

Technical Field

The utility model relates to the technical field of screening equipment processing, in particular to a welding device for a screen disc.

Background

The vibrating screen works by utilizing reciprocating rotary vibration generated by vibrator excitation. The upper rotary weight of the vibrator makes the screen surface produce plane rotary vibration, while the lower rotary weight makes the screen surface produce conical surface rotary vibration, and the combined effect of the upper rotary weight and the lower rotary weight makes the screen surface produce compound rotary vibration. The vibration track is a complex space curve. The curve is projected as a circle on the horizontal plane and as an ellipse on the vertical plane. The vibration force of the upper and lower rotary weights is adjusted to change the amplitude. The curve shape of the movement track of the screen surface and the movement track of the materials on the screen surface can be changed by adjusting the space phase angles of the upper heavy hammer and the lower heavy hammer, so that the screening device is one of the most popular screening devices at present.

The screen plate, which is one of the important components of the vibrating screen, is different in structure and specific function, and is generally formed by a screen, a screen frame, a separating strip or the like, but is mounted on the vibrating screen by welding. Acetylene is generally used as an energy source during welding. Acetylene is an organic compound commonly called wind coal or calcium carbide gas, is the smallest member of the acetylene compound, is colorless gas at normal temperature and pressure, is slightly soluble in water, is soluble in ethanol, acetone, chloroform and benzene, is miscible in diethyl ether, and can be used for oxy-acetylene welding and cutting.
